Tuya plugin PYTUYA no longer working

[PatrickH67]

Hi all,

I am using for years "pytuya" pluging to get access to TUYA device on local network on my Raspberry PI 3 running Domoticz 2022.1 version under "Buster" OS
I have now decided to install the last version of Domoticz 2025.2 on a new Raspberry PI5 running "Trixie"

Domoticz is running fine but I am no longer able to install the plugin "pytuya" on this OS. I have uses VENV on this install but even with this configuration I am not able to install it

I have the following message

  note: This error originates from a subprocess, and is likely not a problem with pip.

As far as I can understand it cannot found module "Crypo" and "pyaes", but if list the install modules they are present

On domotcz startup (/etc/init.d/domoticz.sh) I have added the VENV environment

export PYTHONPATH=/home/admin/Domoticz_Python_Environment:$PYTONPATH

Any advice for solving this issue ?

Thanks
